3. Cigarette Smoke Smell

If Ac smells bad and feels like cigarette smoke, it typically to happen when you smoke inside your home. The evaporator coil and ac filter might accumulate if you smoke inside your home.

5. Moldy, Mildew, or Musty AC Smell

Excessive moisture or humidity in the HVAC system leads your ac smells bad like mildew or musty. If there is a fungus growing around your ac unit, it will make its way through ductwork.
